Description

test_kudu_upsert failed inexplicably on a GVO with an unrelated change. I attached the relevant part of the log. The difference seems to be that two string columns are swapped: 'he' versus 'e'.

40,'e',0,43,'he',false,35,36,1.2,37 != 40,'he',0,43,'e',false,35,36,1.2,37

The job is https://jenkins.impala.io/job/ubuntu-16.04-from-scratch/1495/.

I looped the test overnight to try to reproduce but haven't seen it happen again.
